Flame retardants in transportation industry The world is a much smaller place today thanks to modern modes of transportation. Decisions about vacation destinations or business travel now go beyond cities and states and encompass countries around the world. Travel, whether by car, train or airplane, is faster, safer, more affordable and much more comfortable than ever before. These improvements are largely due to the techn…

Electrical and Electronic Equipment: Types of Flame Retardants Used in EEE Applications Flame retardants are an important component in reducing the devastating impact of fires on people, property and the environment. Their areas of application in electrical and electronic equipment (EEE) vary depending on the materials being used, the function of the product, and the level of fire resistance that must be achieved based on fire safety standards. Flame retardants hav…

The mechanism of flame retardants Flame retardants are functional additives that endow flammable polymers with flame retardancy. They are mainly designed for the flame retardant of polymer materials. They exert their flame retardant effects through several mechanisms, such as heat absorption, coverage, inhibition of chain reactions, and incombustibility. Gas asphyxiation, etc. Most flame retardants work together…

Replacement of lead based stabilizers with lead free stabilizers-3 Until 2016, 80% of the world’s manufacturers were using lead stabilizers, the remaining 20% are used to stabilize PVC food packing, mineral water bottles and pharmaceutical containers. Despite many advantages, the toxicity of lead has brought a restriction to the use of lead based stabilizers in PVC articles. This restriction brought a revolutionary change in PVC processing. In…

Replacement of lead based stabilizers with lead free stabilizers-2 Besides Ca-Zn stabilizers, Organotin mercaptide based stabilizers are another choice. These are generally available in liquid form, but nowadays powder form is also available with some manufacturers. Organotin stabilizers are very popular for transparent applications and rigid applications in America. They offer outstanding color retention in plasticized and rigid PVC processing…

Replacement of lead based stabilizers with lead free stabilizers-1 Nathaniel Branden, a famous Canadian-American psychologist once said, “The first step toward change is awareness. The second step is acceptance.”Lead based stabilizers are being used from the very beginning to stabilize rigid PVC across the world. The decomposition temperature of PVC is much lower than its processing temperature. Thus, the processing of PVC requires heat stabi…

FLAME RETARDANTS AND THE FUTURE It’s famously said “Prediction is very difficult, especiallyif it’s about the future.” Fire safety will surely remain a primaryrequirement for electronic and electrical equipment. In orderto ensure fire safety, there will be a need to incorporate flameretardants into plastic systems forming part of such electronic and
